Seco 17015185 Roughing End Mill 3/4 in 4 Flute Cobalt Ticn

Product Description

The SECO 17015185 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel and finished with a TiCN coating, it delivers elevated heat and wear resistance compared to standard HSS tooling. The cutter measures 0.75 inches in diameter with a 1.25-inch length of cut and a 3.5-inch overall length. Four right-hand spiral flutes with a 30-degree maximum helix angle channel chips efficiently during roughing passes. This tool is installed and operated by machinists and tool-and-die professionals working on CNC or manual milling machines.

The 17015185 is suited for short-reach roughing operations on ferrous and non-ferrous materials where high feed rates and rapid stock removal are the priority. Its TiCN coating adds surface hardness and lubricity, extending tool life in interrupted cuts and hard-material applications. The 0.75-inch shank diameter matches the cutter diameter for direct collet or end mill holder mounting without reduction. This is a right-hand cutting, right-hand flute configuration in the SECO REM710 series, built to short length-type standards for maximum rigidity.

Key Features

• M42 cobalt steel construction for improved red hardness over standard M2 HSS
• TiCN coating extends wear life and reduces heat buildup at the cutting edge
• 4 right-hand spiral flutes with 30-degree helix for efficient chip evacuation
• Single-end design with 1.25-inch length of cut and 3.5-inch overall length
• Short length-type geometry maximizes rigidity during heavy roughing passes
• Non-center-cutting — requires a pilot hole or side-entry engagement

Compatibility

Designed as an OEM-style roughing end mill for use in standard 3/4-inch collets or end mill holders on CNC or manual vertical milling machines. Part of the SECO REM710 series.

Installation Notes

This end mill is installed by machinists using a 3/4-inch collet chuck or end mill holder; ensure the holder is clean and free of debris before seating the shank. This tool is not center-cutting — do not plunge directly into solid material; use a ramping or side-entry approach. Verify spindle speed and feed rate against the material being machined before engaging the cut. Follow shop safety protocols and machine guarding requirements during all milling operations.
